Color & Background

The text-bg-* helpers set a theme background together with a readable, contrasting text colour in one class. Use them for badges, tiles, banners and status labels when you want the pairing to stay accessible in every colour scheme.

1Every theme colour as a badge

One text-bg-* class sets the background and a contrasting text colour together.
